The raceways of both the inner and outer rings of this bearing type are made with a set contact angle.

Single-row Angular Contact ball bearings can sustain radial, axial or composite loads, however, any axial load must be in one direction.
Larger contact angle type has better axial load capability.
Small contact angle type has higher permissible speed capability. This bearing type is generally used in adjacent positions.

The raceways of both the inner and outer rings of this bearing type are made with a set contact angle.

These bearings are non-separable. Since the balls are inserted utilizing counter-bore construction, a larger number of balls can be installed than in the case of Deep Groove ball bearings.

Standard cage materials may be pressed steel, high- strength brass, or polyamide. Cage materials is dependant on the bearing series and or service condition. Single-row Angular Contact ball bearings can sustain radial, axial or composite loads, however, any axial load must be in one direction. This bearing type is generally used in pairs to handle the induced load resulting from the internal axial force generated by the applied radial load. When mounting two single bearings in adjacent positions, NACHI provides these combination parts (pairs) with preadjusted clearance. Paired combination bearings are matched sets. Combination or paired bearings can be arranged BACK-TO-BACK (DB), FACE-TO-FACE(DF), or in TANDEM (DT). DB or DF sets can sustain bidirectional axial loads.
